The quarter finals have arrived! Eight powerful, popular DC Comics super heroes (or if you want to be technical, seven heroes and one infamous villain) have advanced beyond the preliminaries into the second round. But the fights just get tougher from here. Need proof? Look no further than our first match-up: Batman vs. Wonder Woman. Two friends and teammates. But there are no friends in the Battle Arena. Will Bruce break out those toys of his against the Amazonian princess? Or will Diana lasso up another amazing victory? Meanwhile, in our second quarter final match-up, the Flash tries to quickly put down the Joker. Easier said than done...
